Publish Component Button

[jmakowski1123]

The Publish component button (in the manage tab of the component sidebar) should be clickable in the following scenarios:

• When a new component has been created and saved
• When a component has been modified and saved

The Publish component button should not be clickable (grayed out, but still visible) in the following scenarios:

• When a component has not been modified since the last time it was published

Expected behavior:

• When the Publish button is clicked, the component is available for reuse in courses.
• Content that has never been published is not available for reuse in courses.
• Content that has been published, later modified but not republished is not available in its modified version for reuse in courses, but the previously published version is available.

Syncing:

• When library content being used in a course is modified and published in a library, that triggers the sync workflow in courses, here Review and accept/deny content syncs #1341

There's no Learning Core API to publish exactly one thing, but publish_drafts accepts a QuerySet of Drafts. So with no changes to openedx-learning, we could do something like:

pe_key = pe_key_from_usage_key(usage_key)  # I'm just making this up, but we have a mapping somewhere
drafts_to_publish = authoring.get_all_drafts(learning_package_id).filter(entity__key=pe_key)
authoring.publish_drafts(learning_package_id, drafts_to_publish, published_by=user.id)

@ormsbee I think you mean publish_from_drafts? there's a publish_all_drafts in the public learning core API, but publish_from_drafts isn't public, it's just available for internal learning core apps. I can still do from openedx_learning.apps.authoring.publishing.api import publish_from_drafts, but I guess it'd be better to add it to the exported functions inside __all__ right?

@DanielVZ96: Yes, I meant publish_from_drafts, and I had forgotten that it wasn't public. Please feel free to tag me on the openedx-learning PR to make it public. Thank you.
